The HVAC Valuation Reality: Why Most Owners Undervalue Their Business
Here's a statistic that surprises most HVAC contractors: the average HVAC business owner underestimates their company's value by 40–60% when using informal calculations. Meanwhile, private equity firms have never been more aggressive in acquiring well-run HVAC companies.
As of early 2026, HVAC valuation multiples have increased approximately 20% from pre-pandemic levels, driven by private equity rollups, recurring revenue premiums, climate-driven demand, and consolidation trends.
| Business Profile | SDE Multiple | EBITDA Multiple | Valuation |
|---|---|---|---|
| Small ($200K–$500K SDE) | 2.6x–3.5x | 3.5x–4.5x | $520K–$1.75M |
| Mid-Size ($500K–$1.5M SDE) | 3.5x–4.5x | 4.5x–6x | $1.75M–$9M |
| Large ($1.5M+ EBITDA) | 4.5x–5.1x | 6x–10x | $9M–$50M+ |
| PE Platform ($2M+ EBITDA) | — | 8x–12x | $16M–$100M+ |
The difference between a 3× and 6× multiple on a $1M EBITDA business is $3 million in your pocket.
HVAC Business Valuation Fundamentals: SDE vs. EBITDA
What Is SDE (Seller's Discretionary Earnings)?
SDE represents the total financial benefit a single owner-operator receives. It's the standard for businesses under $1M in earnings.
SDE Formula:
SDE = Net Income + Owner's Salary + Personal Expenses + Depreciation + Interest + One-Time Expenses
Example SDE Calculation:
| Net Income | $185,000 |
| Owner's W-2 Salary | $85,000 |
| Health Insurance | $12,000 |
| Vehicle Personal Use | $8,000 |
| Depreciation | $35,000 |
| Interest Expense | $6,000 |
| One-Time Purchase | $15,000 |
| Total SDE | $346,000 |
At 3.2× SDE: $1,107,000 valuation
What Is EBITDA?
EBITDA measures operational profitability. It's the standard for businesses over $1M earnings and PE buyers.
Critical Difference
With EBITDA, add back a market-rate owner replacement salary ($100K–$150K). This reflects true operational earnings a new owner would receive.
| Factor | Use SDE | Use EBITDA |
|---|---|---|
| Annual Earnings | Under $1M | Over $1M |
| Owner Role | Active operator | Passive owner |
| Buyer Type | Individual | Private equity |
| Typical Multiple | 2.6x–4.5x | 4x–10x |
